Relevant Experiences

I have conducted several ship machinery troubleshooting contracts for the US Navy, which have taken me to Oahu on occasion.

I have worked for TECO Westinghouse, which has manufactured portions of wind turbines. My interest areas were various portions of the generator, including the bearings and the controls.

I have been trained in welding, both arc and gas types. I have both wire and stick welders in my workshop. Also, I have studied machine safety for a number of years. Moreover, my experience in troubleshooting of a range of machinery and equipment types allows me to quickly come up to speed on new requirements.

I have personal experience with very large, slow speed engines used in ship propulsion. Also, I have experience with smaller higher speed engines (V-16) used for generation of electric power aboard US Navy surface combatant ships.
